U STATES FRIEDRICH BRAUNLIOH, OF AUSSIG 'A/E, CZECHOSLOVAKIA, ASSIGN OR TO SOCIETY OF CHEMICAL INDUSTRY IN BASLE, OF BASEL, SWITZERLAND PREPARATION OIE NEW MOUTH WASHES AN D DENTIFRICES No Drawing. Application filed October 7, 1926, Serial No. 140,211, and in Czechoslovakia October 14, 1925.

My invention relates to the preparation of newlmouth washes and dentifrices.

Apart from the mouth washes which are used to a large extent only because of their pleasant flavour, practically the only other preparations which come into question for treating the mouth and teeth are the varlous dental soaps and tooth pastes and powders containing more or less soap and in many cases also containing no soap. The eflect obtained by these difiere nt preparations is due largely or exclusively to the mechanical action of the inorganic scouring agents contained therein, such as chalk, magnesia, pumicestone and the like, which action only in the case of the preparations containing soap, is assisted and improved-as regards the detrimental results of the purely mechanical scouring action-by the known cleansing properties of the added soap. Experience has shown that, these preparations do not have a specific teeth cleansing action under the conditions in which they are used. They are more especially unable to prevent the deposit of tartar deposits of insoluble calcareous salts com ined with organic substances) which has sucha destructive eflect upon the teeth.

The object of the present invention is the use of sulphonated fats or of sulphonated fatty acids as well as of the alkali and am- 7 monium salts of these compounds for producing very efiective mouth and dental cleanslng agents. Their specific action which is very pronounced in this respect is based:

1. On the strong dissolving capacity of these sulpho-fatty acid compoundsboth for fatty as well as for substances soluble in water,

2. On their specific ca acity of dissolving tartar on the teeth or o preventing its formation, 7

3. On their great capacity for emulsifying, which enables them' also to emulsify as colloids or convert into solutions impurities that are insoluble in tlcuernselves In'addition, owing to their strong lipotropic properties, they have more powerful dis nfecting action than'iordinary soaps, with V I which they have in common in the term of the alkali salts not only their chemical character, but also the property of being entirely harmless to the human organism and the vital cells. V

The combination of these valuable properties makes the said sulpho-fatty acid compounds suitable as basis for the production of eflective mouth washes and dentifrices, which, as has been found by lengthy observation, exert their specific properties to a full extent also under the conditions of daily use.

They are applied either in the'form of an addition to the usual mouth washes and dentifrices of any composition and nature or in a pure form in any desired degree of concentration. c

According to one mode of carrying the invention into effect by way of example, 5 parts by weight of Turkey red oil are added to 95 parts by weight of a tooth paste of any desired composition and thereupon worked up to a further extent in a known manner.

According to another mode of carrying the invention into efi'ect with the object of producing an agent which can be used at the same time as mouth wash and as a dentifrice, 96 parts by weight of Turkey red oil of 50% fat content, 2 parts by weight of peppermint oil and 2 parts by weight of aniseed oil are combined to form a liquid.

What I claimis: I

1. A dent-ifrice having as an ingredient a salt of a sulphonated castor oil soluble in water. I v v 2. A dentrifrice comprised of a tooth paste containing Turkey red oil.

3. A dentifrice comprising 5 parts by weight of Turkey red oil and 95 parts by weight of a tooth paste.

' In testimony whereof I afix my signature.
